We can prove his premises inconsistent with Scripture, but they not themselves illogical.
The Holy Scriptures are the product of "Logos;" thus we contend any philosophy or human thought that departs from Holy Scripture, cannot prove to be consistently logical, for any length of time.
An erroneous premise may provide a long-lasting argument, that appears logical, but eventually it will prove to be only temporal and illogical in the light of Godly truth.
An argument can be valid and consistent without the conclusion necessarily being true.
As in:
1. All who trust in a false gospel are lost
2. All Arminians are trusting in a false gospel
3. All Arminians are lost
This logical argument is consistent and its conclusion is valid. However its conclusion is false. The point of breakdown is in the second premise. Not all Arminians are trusting in a false gospel. Remember, Arminians hold to numerous self-conflicting propositions.
